Intramuscular Neural Distribution of the Sartorius Muscles: Treating Spasticity with Botulinum Neurotoxin
Intramuscular Neural Distribution of the Sartorius Muscles: Treating Spasticity With Botulinum Neurotoxin Kyu-Ho Yi Yonsei University Ji-Hyun Lee Yonsei University Kyle Seo Modelo Clinic Hee-Jin Kim ( [email protected] ) Yonsei University Research Article Keywords: botulinum neurotoxin, spasticity, sartorius muscle, Sihler’s staining Posted Date: January 6th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-129928/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/14 Abstract This study aimed to detect the idyllic locations for botulinum neurotoxin injection by analyzing the intramuscular neural distributions of the sartorius muscles. A altered Sihler’s staining was conducted on sartorius muscles (15 specimens). The nerve entry points and intramuscular arborization areas were measured as a percentage of the total distance from the most prominent point of the anterior superior iliac spine (0%) to the medial femoral epicondyle (100%). Intramuscular neural distribution were densely detected at 20–40% and 60–80% for the sartorius muscles. The result suggests that the treatment of sartorius muscle spasticity requires botulinum neurotoxin injections in particular locations. These locations, corresponding to the locations of maximum arborization, are suggested as the most safest and effective points for botulinum neurotoxin injection. Introduction Spasticity is a main contributor to functional loss in patients with impaired central nervous system, such as in stroke, cerebral palsy, multiple sclerosis, traumatic brain injury, spinal cord injury, and others 1. Sartorius muscle, as a hip and knee exor, is one of the commonly involved muscles, and long-lasting spasticity of the muscle results in abnormalities secondary to muscle hyperactivity, affecting lower levels of functions, such as impairment of gait.

Vascular Injury Following Harvesting of Hamstring Tendon Graft for Anterior Cruciate Ligament Reconstruction
Central Annals of Orthopedics & Rheumatology Bringing Excellence in Open Access Case Report *Corresponding author Bruno Pavei, Hospital de Clínicas de Porto Alegre, Porto Alegre, Rio Grande do Sul, Brazil, Email: Vascular Injury Following Submitted: 27 February 2018 Accepted: 10 March 2018 Harvesting of Hamstring Published: 12 March 2018 Copyright Tendon Graft for Anterior © 2018 Pavei OPEN ACCESS Cruciate Ligament Keywords • Knee injuries • Anterior cruciate ligament Reconstruction • Vascular injury Bruno Pavei* Hospital de Clínicas de Porto Alegre, Porto Alegre, Rio Grande do Sul, Brazil Abstract Objectives: To describe a rare case of significant vascular injury that occurred following the harvest of hamstring tendon graft for anterior cruciate ligament reconstruction, with the need of repair. Case report: A 30-year-old male soccer player presented with significant swelling and acute pain two hours after anterior cruciate ligament (ACL) reconstruction. Clinical examination and MRI scan showed bleeding, and a large hematoma in the middle of the left thigh. Hemorrhagic contention was only possible after a secondary repair, where a vessel of the sartorius muscle was bleeding profusely 12 hours after the primary surgery. Discussion: The presence of a large number of vessels on the medial side of the knee associated with blind flexor tendons graft hamstring is cause of vascular injury during removal of the hamstring graft. Conclusion: Although uncommon, graft hamstring of flexor tendons can have devastating consequences if some hemostasis procedures are not correctly applied. INTRODUCTION CASE REPORT Anterior cruciate ligament (ACL) is the most commonly A 30-year-old male soccer player presented with an ACL injured ligament of the knee.

Thigh Muscles
Lecture 14 THIGH MUSCLES ANTERIOR and Medial COMPARTMENT BY Dr Farooq Khan Aurakzai PMC Dated: 03.08.2021 INTRODUCTION What are the muscle compartments? The limbs can be divided into segments. If these segments are cut transversely, it is apparent that they are divided into multiple sections. These are called fascial compartments, and are formed by tough connective tissue septa. Compartments are groupings of muscles, nerves, and blood vessels in your arms and legs. INTRODUCTION to the thigh Muscles The musculature of the thigh can be split into three sections by intermuscular septas in to; Anterior compartment Medial compartment and Posterior compartment. Each compartment has a distinct innervation and function. • The Anterior compartment muscle are the flexors of hip and extensors of knee. • The Medial compartment muscle are adductors of thigh. • The Posterior compartment muscle are extensor of hip and flexors of knee. Anterior Muscles of thigh The muscles in the anterior compartment of the thigh are innervated by the femoral nerve (L2-L4), and as a general rule, act to extend the leg at the knee joint. There are three major muscles in the anterior thigh –: • The pectineus, • Sartorius and • Quadriceps femoris. In addition to these, the end of the iliopsoas muscle passes into the anterior compartment. ANTERIOR COMPARTMENT MUSCLE 1. SARTORIUS Is a long strap like and the most superficial muscle of the thigh descends obliquely Is making one of the tendon of Pes anserinus . In the upper 1/3 of the thigh the med margin of it makes the lat margin of Femoral triangle. Origin: Anterior superior iliac spine.

Iliopsoas Muscle Injury in Dogs
Revised January 2014 3 CE Credits Iliopsoas Muscle Injury in Dogs Quentin Cabon, DMV, IPSAV Centre Vétérinaire DMV Montréal, Quebec Christian Bolliger, Dr.med.vet, DACVS, DECVS Central Victoria Veterinary Hospital Victoria, British Columbia Abstract: The iliopsoas muscle is formed by the psoas major and iliacus muscles. Due to its length and diameter, the iliopsoas muscle is an important flexor and stabilizer of the hip joint and the vertebral column. Traumatic acute and chronic myopathies of the iliopsoas muscle are commonly diagnosed by digital palpation during the orthopedic examination. Clinical presentations range from gait abnormalities, lameness, and decreased hip joint extension to irreversible fibrotic contracture of the muscle. Rehabilitation of canine patients has to consider the inciting cause, the severity of pathology, and the presence of muscular imbalances. ontrary to human literature, few veterinary articles have been Box 2.

Femoral Sheath • This Oval, Funnel-Shaped Fascial Tube Encloses the Proximal Parts of the Femoral Vessels, Which Lie Inferior to the Inguinal Ligament
Femoral Sheath • This oval, funnel-shaped fascial tube encloses the proximal parts of the femoral vessels, which lie inferior to the inguinal ligament. • It is a diverticulum or inferior prolongation of the fasciae lining of the abdomen (trasversalis fascia anteriorly and iliac fascia posteriorly). • It is covered by the fascia lata. • Its presence allows the femoral artery and vein to glide in and out, deep to the inguinal ligament, during movements of the hip joint. • The sheath does not project into the thigh when the thigh is fully flexed, but is drawn further into the femoral triangle when the thigh is extended. Subdivided by two vertical septa into three compartments: • (1) Lateral compartment for femoral artery • (2) Intermediate compartment for femoral vein • (3) Medial compartment or space called femoral canal. Femoral Triangle Clinically important triangular subfascial space in the superomedial one-third part of the thigh. Boundaries: • Superiorly by the inguinal ligament • Medially by the medial border of the adductor longus muscle • Laterally by the medial border of the sartorius muscle • T h e m u s c u l a r f The muscular floor is not flat but gutter-shaped. • Formed from medial to lateral by the adductor longus, pectineus, and the iliopsoas. • It is the juxtaposition of the iliopsoas and pectineus muscles that forms the deep gutter in the muscular floor. • Roof of the femoral triangle is formed by the fascia lata which includes the cribiform fascia. Contents : • This triangular space in the anterior aspect of the thigh contains femoral artery and its branches • Femoral vein and its tributaries • Femoral nerve and its branches • Lateral cutaneous nerve • Femoral branch of the genitofemoral nerve, • Lymphatic vessels • Some inguinal lymph nodes.
